Q

What is the issues we will commonly see with the anconeal process of the ulna?

A

Doesn’t like to fuse properly due to a low growth plate and when it doesn’t unite you end up with arthritis in that elbow & it is painful

Q

How accessible is the middle carpal joint?

A

opens fully
accessible

17
Q

How accessible is the carpometacarpal joint?

A

does not open widely but it communicates with the middle carpal joint

18
Q

What is the main purpose of the collateral ligaments?

A

prevent medial and lateral motion
these are the ones that get ruptured when a limb takes a hit

19
Q

What is the purpose of the annular ligament of the elbow?

A

supports the rotary action of the head of the radius against the radial notch of the ulna

20
Q

What is a bursa?

A

friction reducer
synovial “pillow” between two high pressure points

21
Q

What is a tendon sheath?

A

are tube like synovial structures that allow smooth operation of the tendons and the sheath is filled with synovial fluid

22
Q

What is the Flexor Manica

A

Where the superficial digital flexor makes and opening for it to reach P2 & the deep digital flexor can continue to P3

23
Q

Where are the extensors of the carpus and digits located and what is their origin?

A

Craniolaterally
Lateral epicondyle of the humerus

24
Q

Where are the flexors of the carpus and digits located and what is their origin?

A

Caudomedially
Medial epicondyle of the humerus

25
Q

What ligament is maintained in hyperextension in cats?

A

Medial dorsal elastic ligament

26
Q

Where do large arteries tend to lie and why?

A

Medial and deep for protection

27
Q

What is collateral or recurrent circulation?

A

Supplemental flow to a region

28
Q

What are the major superficial veins of the thoracic limb and where do they go?

A

Cephalic vein
Accessory cephalic
travel to the head

29
Q

Where does the accessory cephalic vein begin?

A

Dorsally

30
Q

Where does the cephalic vein begin?

A

Palmarly

31
Q

What is the sequence of flow from the Subclavian artery to the median artery?

A

Subclavian
Axillary
Brachial
Median (radial cats)

32
Q

What forms the brachial plexus?

A

formed from ventral branches of certain cervical & thoracic spinal nerves

33
Q

What do nerves first provide and pass toward coming from the brachial plexus?

A

first provide motor branches to ventral neck muscles then pass toward axillary space

34
Q

Why is the radial nerve important?

A

To bear weight, the limb must be in extension. The radial nerve innervates the extensor muscles of the forelimb

35
Q

If a horse can still extend the carpus it is probably a what?

A

Fractured olecronon

36
Q

If a horse CANNOT still extend the carpus it is probably a what?

A

Radial Nerve damage

37
Q

What are the major contributing motor nerves of the manus and where does it go to?

A

Ulnar nerve only
goes to interosseous muscles & other minor muscles of forepaw

38
Q

What are the major contributing sensory nerves of the manus?

A

Radial nerve
Medial nerve
Ulnar nerve

39
Q

What is an autonomous zone and how is it clinically useful?

A

skin region typically supplied by a single spinal nerve

useful for evaluating the integrity of a nerve
